Does d-limonene 1000mg really work for bad acid reflux?

I have been having horrible gerd for about 2 years now. Had h pylori that was successfully cured but the acid reflux is horrible. Chest pain. Shortness of breath all from gerd. I have had heart test to rule out anything severe. Today I read about orange peel extract and decided to give it a try. I was in Prevacid but it gave me horrible heart palps so I stopped it about a year ago and have been suffering since. What are some great products for gerd and has anyone tried d-limonene 1000mg? Thanks

I have tried the d-limonene with some relief once when i ran out of my ppis it helped the last real bad flare i had i think it was called( heartburn free)1000 mgs i also get the real bad chest pain .It scares the heck out me i think i'm having a heart atack unfortunatly there are only a couple of things that work for me when it gets real bad .One is a gi cocktail called grasshopper mylanta and lidocain mixed up like a cough syrup and the other is aciphex a ppi i'm still working on finding that silver bullet
